Alias and CC

I have a requirement to have an email address, say ]accounts@domain.com as an alias to user1@domain.com. On top of this we'd like any emails sent to accounts@domain.com also CC'd to user2 and user3.
I can's see a way to do with with an alias. Will I have to create accounts as a user, and set up forwrads? What about CC's?
